FIG. 10 is an inside view of the lock and latch assembly embodying myinvention as shown in- FIGS. 8 and 9.

In the accompanying drawing applicant has illustrated his invention asadapted to upwardly acting doors ofthe sectional type comprising aplurality of sections 1 conneoted by the hinges 2 which, in theembodiment illustrated, support the rollers 3 which coact with thetracks 4 of inwardly facing channel cross section. A portion 5 of thewall of a garage or the like is conventionally illustrated. It will beunderstood that the tracks are provided with so called overhead portionswhich are not illustrated as they form no part of this invention.

The door is provided with a counterbalance means designated generally bythe numeral 6 which has pulleys 7 for the cables 8. Details of thiscounterbalance means are not illustrated as they form no part of theappl-icants present invention.

Applicants latch or bolt lock means in the embodiment thereof,illustrated in FIGS. 1 to 7, comprises a housing designated generally bythe numeral 9 and including a front wall Iii, top wall 11, bottom wall13 and side Walls 14. The housing in this embodiment is formed as anintegral stamping and the top and bottom walls are provided withoutwardly projecting flanges 15 which. have openings for the attachingscrews 16 by means ofwhich the housing is generally connected to thedoor panel 1. The side walls of the housing have slot-like openings 17therein in which the bolt member 18 is slid ably supported. This boltmember in the embodiment illustrated has an outer section 19 pivotallyconnected thereto at 20.

The embodiment illustrated in FIGS. 1 to 7 is provided with a secondbolt member 21 disposed with its inner end below the housing. These boltmembers 19 and 21 are slidably supported adjacent their outer ends bythe bracket or guide member 22 fixedly secured to the inner side of thedoor. Thebolt coupling member 23 is mounted on the pivot or spindle 24provided with a handle 25 on the outer side of the door, and with ahandle 26 on the inner side of the door, see FIGS. 1, 2 and 3. This boltcoupling and actuating member is actuated to bolt retracted position bymeans of the spring2'7, one end of which is connected to the boltcoupling and actuating means at 28 and the other end to the housing wallat 29, see FIG. 5.

With this arrangement the bolts are retracted by the spring 27 upon thereleasing of catch 30 which is pivotally mounted at 31 on the front wallof the housing which is provided with a bearing 32 therefor, the frontwall being provided with a similar bearing 33 for the spindle 24.

The catch or latch member 36 is actuated to engaged position by thespring 34 connected to the lug 35 on the latch member and to the sidewall at-36;, see FIG. 5. This latch member is provided with afingerpiece 37 projecting through an opening or slot 38 in the top 11 ofthe housing. The housing is provided with a slot 39 in its bottom wallthrough which the bolt coupling and actuating member 23 projects and towhich the inner end of the bolt member 21 is pivotally connected at 40.

The lock barrel 41 is supportedly mounted in the bore 42 in the door.The lock spindle 43 may be adjusted only from the outer side of the dooras by the key 44. The spindle 43 engages the catch member 30 so that itmay be tionship' of the garage to a house or other building. 'ing thesepoints in mind, attention is directed to FIG.

disengaged from the keeper 45 on the bolt coupling and catch in engagedposition, as illustrated in FIG. 5, it cannot be released bymanipulation of the handle 25. in other words, the'handle is locked andalso the bolts cannot be disengaged through the handpiece 26 from theinner side of the door but the latch 30 may be released by the handpiece37 and the bolts are retracted by the spring '27. They maybe adjusted tolocking position from the inside of the door but the latch 30 may bereleased by the handpiece 37and the bolts are retracted by the spring27. They may'be'adjusted to locking position from the inside of thedo'or'by means of the handle 26.

The bolts and coacting parts are illustrated in their retracted positionin dotted lines in FIG. 3. In the embodirnent illustrated the rails areprovided with holes 48 which constitute keepers for the bolts, see FIG.3.

'In'the embodiment of my invention shown in FIGS. 8

'and 9 the door sections Ell are somewhat modified in structure fromthat shown in the other figures but it should be understood that this isnot important as to the structural features of my present invention butit does illus- 'tr'ate a type of door which is in extended commercialuse.

The tracks 4 are substantially those shown in FIGS. 1

and 3.

Theibolt and latch housing and support member 1% of 'this embodiment isthe same as that shown in the embodiment of FIGS. 1 to 7 inclusive.However, it should be understood that the bolt'rnember 51 illustrated inthese FIGURES 8, 9 and 10 has the same shape on both ends and either endis adapted to be engaged with the keeper "4:; of either track. See FIGS.8 and 9.

The handles 25 and 26 on the inner and outer sides of the door are thesame as in the embodiment of FIGS. l-7 inclusive, however, in FIGS. 1-7inclusive two simultaneously actuated bolts are provided for engagementwith both tracks. In the present embodiment a single bolt 51 is providedwhich corresponds generally to the bolt mem- *ber 18 of'FIG. 3.

' It will be noted that in FIG. 8 the lock member is mounted on the lefthand side of the door viewed from the inner side thereof and in FIG. 9it is mounted on the right hand side of the door and in commercialpractice this positioning is varied according to the manner which ismost convenient for manipulation, for example, the rela- Havin which thebolt'is shown projected to the left in the figure but it would beprojected to the right as shown in FIG. 9 when applied to a door.

The latch-member 39 is provided with corresponding lugs 52 uniformlyspaced from the pivot for the latch member and engageable with thekeeper 45.

It shouldbe noted that FIG. 10 corresponds in structural details to FIG;5 with the eXception that the bolt 51 has en d portions, both of whichare adapted to engage a keeper when'in projected position and the onlychange in the "structure is the elimination of the bolts 19 and Z1 andthe shortening 'of the bolt 18 to adapt the structure to jp'ositioningadjacent the track, as is illustrated in F165. '8' and 9.,

It should be understood, as stated, that the embodiment as shownin'FIGS.8, 9 and 10 is an adaptation of my inventionto the use of asingle bolt and that it illustrates that the lock means is adapted to bepositioned on either side of a door. It is a structure more economicalto produce "than that of FIGS. 1-7 inclusive but it does not have bolt 4means for engaging keepers on both sides of the door which is anadvantage in anchoringly locking both sides of the door which varyconsiderably in width.

1 have illustrated and described my invention in highly practicalembodiments thereof. 1 have not illustrated or described otherembodiments or adaptations as it is believed this disclosure will enablethose skilled in the art to embody or adapt the invention as may bedesired for particular installations.
